2007 si transmission maintenance

I have a 2007 Civic si that i just bought not to long ago, I noticed the transmission is very notchy and did some research and found out its probably my synchros. Now my question is should i rebuild it with aftermarket parts or oem parts? Or should I buy a new transmission? Also what is the best and somewhat affordable way?

Synchrotech or geardriven sell rebuilt transmissions that you can swap out and send back the core. That has the least downtime. Otherwise the synchrotech master rebuild kit for any Honda transmission is great if you want to learn to rebuild one.
Synchros help with gear shifts when the rpms are different between gears. It synchronizes the speeds so they mesh without grinding.
